MACHINE FOR MAKING PERFORATED MUSIC.

SPECIFICATION forming part of Letters Patent No. 791,481, dated June 6, 1905.

Application filed March 14, 1903. Serial No. 147.768.

To all whom it may concern:

Be it known that I, PHILIP J. MEAIIL, a citizen of the United States of America, and a resident of Chicago, Cook county, Illinois, have invented a certain new and useful .Improvement in Machines for Making Perforated Music, of which the following is a specification.

One of the most important features or elements of an automatic piano-player is the sheet of so-called perforated music, which travels slowly over the tracker-board while the player is in operation.

Generally stated, the object of this invention is to provide an improved and highly-efficient machine for making the said perforated music.

A special object is to provide an improved construction and arrangement whereby the perforations in a pattern or master-sheet may be reproduced in several sheets of paper at a time with great accuracy and with as much rapidity as is practicable in a machine of this character.

Another object is to provide an improved machine of such nature and 'modeof operation as will permit of the use of an ordinary piece of perforated music as the pattern or mastersheet and which will permit of the use of a master-sheet of comparatively thin paper.

A further object is to provide improved means for insuring an accurate and proper intermittent feeding movement of the mastersheet and also of the paper in which the perforations of the master-sheet are being reproduced and for preventing the maintenance of any tension or pull upon the paper-rolls during the operation of the machine.

It is'also an object to provide certain details and features of improvement tending to increase the general. efficiency of a machine ofthis character and tending to reduce the cost of perforated music.

To the foregoing and other useful ends my invention may be embodied in practical form,

' as hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a machine for making perforatedmusic and embodying the principles of my invention. Fig. 2 is a perspective of' a sliding block to which the ends of both the v I master-sheet and the strips of paper are attached for the'purpose of giving the same an intermittent feed, and also of the adjacent portions of the tracks or ways in which the said block slides. Fig. 3 is alongitudinal section through the forward and upper portion of the machine on line 3 3 in Fig. 5. Fig. 4:

is a plan of the portion of the machine shown in Fig. 3, certain portions being broken away for convenience of illustration and the lower half of the view being in horizontal section.

Fig. 5 is a front elevation of the portion of the machine shown in Fig. 4, the middle portion being broken away for convenience of illustration and the left-hand portion of the master-sheet being broken away for the purpose of exposing to view certain portions to the rear of the master-sheet. Fig. 5 is a perspective of the upper portion of the self-contained element or structure which constitutes the die and the punches, together with the forward end of one .of the punch-actuators, the middle portion of the punch and die structure being broken away for the purpose of showing theinterior construction. Fig. 7 is a fragmentary perspective view of the upper ends selectors against movement during the operation of the punches. Fig. 8 is a fragmentary perspective view of a portion of the mastersheet, a portion of the tracker-board, and of one of the presser-feet which bear upon the marginal portions of the master-sheet to keep the same in a smooth and proper condition. Fig. 9 is an enlarged side elevation of one of the constantly-vibrating hammers for operating the punches, together with the adjacent portion of the actuating-bar upon which the said hammer or impact device is mounted. Fig. 10 is an enlarged side elevation of the adjustable crank-pin arrangement which constitutes a part of the mechanism for intermittently feeding the master-sheet and paper. Fig. 11 is a section on line 11 11in Fig. 10. Fig. 12 is a vertical section of one side of the machine on line 12 12 in Fig. 3.

The machine thus illustrated is adapted for reproducing the perforations or openings of a piece of perforated music such, for example, as a pattern or master-sheetin one or more strips of paper. In other words, the machine is designed for the purpose of manufacturing perforated music through the medium of a pattern or master-sheet that is to say. the instrumentalities for making the perforations in the strip or strips of paper are controlled by a perforated sheet of paper which is called a pattern or mastersheet and which is provided with perforations corresponding substantially, as far as general size and location are concerned, with the perforations to be made in the strip or strips of paper. It is obvious, however, as will hereinafter more fully appear. that the improved arrangement and method of operating the punches may be employed in conjunction with difl'erent kinds of patterns or master-sheets and that the punching or perforating instrumentalities may be controlled in various ways without departing from the spirit of my invention. In other words, the hereinafter-described punching or perforating devices, operated by hammers hung on a pivoted support, may be employed in either reproducers or in combination with means for manually controlling the operation of the perforating means.

For the purpose of reproducing or manufacturing the perforated music by the aid of a pattern or master-sheet the machine may comprise a suitable body-frame 1, adapted to support the various operative parts in suitably-elevated positions, and adapted to afford suitable bearings for the various shafts and rolls. The unitary and self-contained die-andpunch structure 2 is adapted to extend transversely across the machine and is preferably composed of a base 3, a die-plate 4:, provided with a row of die-openings 5. and a pair of bars 6 and 7 separated by distance-pieces 8 and 9 and provided with a plurality of vertically-movable punches 10, correspondingin number and location to the die-openings 5 in the die-plate. These punches are preferably maintained in their normally elevated positions by the springs 11, each spring having one end inserted in the bar 7 and the other end inserted through its allotted punch. As will be observed by referring to Figs. 1 and 3 and also to Fig. 12, the said unitary and self-contained die-and-punch structure is adapted to have its ends extend through openings in the side pieces of the body-frame and is preferably held in place by set-screws 12 and 13. These screws can be inserted through a flange or thickened portion of the frame, extending around the margins of the said openings in the sides of the frame. With this arrangement the punches and the die can be removed from and replaced in the machine as a unit. This obviously is of great advantage, as it makes it possible to very easily and readily repair and replace any of the punches which may become worn or impaired by usage and also to repair or replace the die.

The tracker-board 14 is preferably arranged vertically at the forward end of the machine and substantially in front of the punch-anddie structure. The said tracker-board may consist simply of one or more plates of metal or other suitable material secured at opposite sides to the two side pieces of the frame or body. If desired, the said tracker-board may comprise two plates arranged edge to edge, the edge of one plate being provided with a row of notches. With this construction, the two plates when placed edge to edge, as shown in the drawings, will provide the face of the tracker-board with a horizontal row or series of tracker-board openings 15. In order to hold the pattern or master-sheet perfectly smooth and fiat while it travels upwardly over the face of the tracker-board, the forward portion of the frame or body of the machine can be provided with the horizontal bars 16, 17, and 18, arranged substantially as shown in Figs. 3 and 5. The upper bar 16 can be provided with a pair of presser-feet 19, adapted to bear upon the marginal portions of the pattern or master-sheet, while the lower bar 18 can be provided with a similar pair of presserfeet 20. The intermediate horizontal bar 17 is preferably provided with a bent plate 21, which also bears upon the pattern or mastersheet from one side to the other and which is provided with a horizontal slot 22, extending opposite and for the full length of the said row or series of tracker-board openings.

For the broader purposes of my invention the pattern or master-sheet may be of any suitable known or approved character. Preferably, however, and as a matter of further improvement the said master-sheet 23 is reinforced at its edges or marginal portions by the strips 24:, and in addition the thus-thickened edge portions of the master-sheet are provided with teeth 25. These teeth are adapted to engage and mesh with the teeth of the two oppositely arranged idlers 26, which are mounted upon the face of the tracker-board. In this way the master-sheet is materially strengthened along its edges and marginal portions, and in addition the toothed idlers cooperate with the teeth out in the edges of the master-sheet in insuring a proper and accurate feeding movement. The teeth at the edges of the master-sheet can, it will be understood, be arranged to correspond with the units of feed, the master-sheet, as will hereinafter more fully appear, having an intermittentfeeding movement in an upward direction upon the face or front surface of the trackerboard. The master-sheet can be fed from the roll 27 at the front of the machine and after passing upwardly across the face of the tracker-board can then be led over the rolls 28, 29, and 30 and thence forward in unison with the sheets of paper.

ITO

The punches are naturally inert or stationary; but the actuators 31 are designed for constant vibration during the operation of the machine, each actuator consisting of a flat bar pivoted or fulcrumed at its rear end upon the shaft or rod 32. These actuators thus mounted for vertical swing or vibration at their forward ends correspond, of course, in number to the punches, the forward endof each actuator being arranged for vertical swing or vibration directly above the upper end of a punch. The shaft or rod 32 can be suitably supported at its ends in the side pieces of the frame or body, as is also the case with the rotary actuating-shaft 33. preferably arranged directly above the forward ends of the vibratory actuators and is connected with the rod 34, which passes through the forward ends of the actuators through the medium of a pair of verticallyreciprocating eccentrically-operated pitmen 35. This driving-shaft 33 isadapted for constant rotation during the operation of the machine, and hence the operation of the machine will be accompanied by a constant upand-down movement or vibration of the actuators 31. Preferably these actuators are, as stated, each in the form of a fiat bar and are all strung upon the two rods 32 and 34, their flat sides bearing against each other without any interposed washers or other means of separation. Each actuator is provided at its forward end with a depending hammer or impact device 36, which is pivoted at its upper end in a recess in the lower edge of the actuator and which is of a length to have'its lower end occupy a position above and quite near to the upper end of its allotted punch. Preferably the upper end of each hammer or impact device is so pivoted and arranged Within the recess that the pivot is relieved of all strain, the upper end of the hammer or impact device bearing directly against the upper end of the top wall of the cavity in which it is pivoted and the said'upper end portion being preferably rounded or cutaway in the manner shown inFig. 9. The means through the medium of which the pattern or master-sheet controls the operation of the said punches consists, preferably, of a plurality of vertically-disposed selectors 37 These selectors can havetheir lower ends strung upon a rod or bar 38, which has its end portions suitably supported in the side pieces of the-frame and which thus provides the selectors with a support, about which their upper ends are free to swing. It will be observed that these selectors are arranged in a row immediately back of the tracker-board and that they are subject-to the tension of the springs 39, which tend to d raw their upper ends forward against the tracker-board. The I upper end of each selector is preferably provided with a finger 40, whichprojects forward from the said upper end of the selector and which is adapted to This shaft 33 ispass through one of the openings 15 in the" tracker-board and also through the slot 22 in the guard or 'presser-strip 21. These selec tors correspond in number to the openings in the tracker-board and also to the number of punches. In other words, there is a selector for each punch. In order that there may be no lateral movement or sidewisedisplacement of the upper ends of the selectors, each fin ger 40 is adapted to accurately fit its alloted tracker-board opening horizontally, but not vertically, and, furthermore, these fingers are preferably slightly narrower than the openings in the master-sheet. In this way it is not possible for the fingers to catch on the edges of the perforations of the master-sheet. Each selector is preferably connected, through the medium of a rod 41, with the hammer or impact device allotted to the corresponding punch. Thus a vibratory or swinging movement of the selector is necessarily accompanied by a vibratory or swinging movement of the corresponding hammen 1 The upper end of'each selector can be provided with notches 42 and 43, adapted to receive the double-beveled knife-edge of the locking-bar 44. This locking-bar is preferably mounted for a partial rotation upon the rod or shaft 45 and is connected with the shaft 46 through themedium of the crank-arms 47 and the connecting-rods 48. Another arm 49 on the outer end of this shaft is adapted to engage the periphery of the cam 50, mounted on the driving-shaft 33. This cam is provided with the node 51, whereby the rotation of the driving-shaft will give the shaft 46 an intermittent oscillatory motion, and this oscillation of the shaft 46 will of course result in an intermittent up-and-down movement of the locking-bar44. Furthermore, thesliding and horizontally-arranged bar 52, which is provided. for the purpose of rendering all of the hammers 36 inoperative during the, feeding movement of the master-sheet and paper, is also given an intermittent shifting movement from this shaft 46 through the'medium of the connecting-rods 53 and the crank-arms j 47. This bar 52 can have its ends supported in guideways 54, substantially as shown in the drawings.

The intermittent forward feeding movement of themaster-sheet is preferably accomplished or other flexible connection preferably eX- tends forward from the said block around the sheave 59 and thence to the said windingdrum. This drum can be given an intermittent rotary movement through the medium of an ad ustable crank-pin 60, working in a slot 61 in the upper end of the bar 62, which latter has its lowerend fulcrumed or pivoted upon the shaft upon which the winding-drum is mounted. The vibratory movement of the arm 62 resulting from the rotation of the driving-shaft 33 is converted into an intermittent rotary motion on the part of the drum through the medium of the pawl 63, which is mounted on said arm, and the ratchet-wheel 64, which is mounted on the shaft of the drum. Consequently the rotation of the driving-shaft is, through the medium of the said instrumentalities, converted into an intermittent forward sliding movement on the part of the block 57. The master-sheet after passing over the roll 30 can be brought downwardly and under the winding-drum 55 and can then have its end firmly secured to the small block 65, which is adjustably mounted upon the main block 57. The adjustment of the block 65 can be effected through the medium of the rotary adjusting-screws 66. After the end of the master-sheet is secured to this block 65 the latter can then be properly adjusted so as to take up any slack which might exist in the forward end portion of the master-sheet and so as to insure at the start the proper relation between the master-sheet and the sheets of paper in which the punches are to reproduce the apertures of the master-sheet. As previously stated, the machine is capable of turning out either one or a plurality of sheets of perforated music at a time-that is to say, the punches may operate upon either one or a plurality of superimposed sheets of paper. The forward ends of the strips of paper can be secured to the block 57, as shown in Fig. 1. It will be understood that the guideways thus provided with the sliding block 57 can be of any suitable or desired length. It may be of such length as to make it necessary to have the sliding block 58 travel but once from the machine to the rear end of the guideway during the operation of making several pieces of music, or if this is impracticable then the guideway can be shortened, so that it will be necessary to draw the block back several times and to refasten the master -sheet and paper at different points along their lengths, during the operation of perforating the req uisite lengths of paper for any particular musical composition.

The strips of paper can be fed over the roll 67, thence between the bar 7 and the die 4, and thence under the roll 68. The relative arrangement of the roll 67 and the die, as shown in the drawings, can be of a character to insure the requisite amount of tension for keeping the sheets or strips of paper flat and smooth and in their proper relative positions during the progress of their passage over the die and below the punches. Therefore and in order to relieve the feed-rolls 69, upon which the various sheets of paper are mounted, from all injurious strain or draft the power-transmitting connection 70 between the said rolls and the drum-shaft 71 is so adjusted that the said rolls and the sliding block 57 operate in unison, each intermittent rotation of the rolls in unison feeding the same amount of paper as is drawn forward by the accompanying forward movement of the block 57 This makes it possible to preserve a certain amount of slack in the paper between the feed-rolls and the roll 67 and to thereby, as stated, relieve the said rolls of all injurious tension or draft. In fact, with this arrangement there is no draft or tension whatever on the paper between the feed-rolls and the roll 67, the tension or friction necessary for maintaining the sheets of paper in a perfectly smooth or flat condition while passing over the die occurring after the paper leaves the roll 67, and if the friction or drag is not sufficient with this arrangement then in such case the roll 67 can be mounted rigidly and held against any rotation whatever. Further friction or drag can be insured by preventing rotation on the part of the roll 68.

It will be readily understood that any suitable power-transmitting connection can be employed for connecting up the feed-rolls 69 with each other and for connecting the rolls thus geared to rotate in unison with the intermittent-feeding shaft 71.

In operation the master-sheet is caused to move upward by steps upon the face of the tracker-board 14, the proper units of feed being determined by adjusting the crank-pin 60. Each time the master-sheet stops the selectors 37 are then released, the lingers of those selectors which are opposite to any perforations in the master-sheet passing through such perforations and carrying certain of the hammers 36 into position to engage the corresponding punches. The locking-bar 44 then engages the notched upper ends of the selectors to hold them against further movement one way or the other, the pressure of the double-beveled edge of the locking-bar in the V-shaped notches in the selectors operating to draw the fingers of those selectors which are not in apertures in the master-sheet slightly away from the surface of the latter and to hold those selectors which are engaging apertures in the master-sheet firmly against movement. The selectors which are not engaging apertures in the master-sheet cause the hammers 36 with which they are connected to remain out of position to engage the corresponding punches, while the selectors which are in engagement with the apertures in the master-sheet hold the other hammers 36 in position to descend upon the upper ends of the corresponding punches. Thus when the actuators 31 descend certain of the punches will be operated, while the balance of the punches will remain in their normal positions. In other words, only such punches as correspond to the hammers connected with selectors engaging apertures 1n the mastersheet Wlll be driven through the paper and into the master-sheet.

the die-openings in the die-plate. Upon further rotation of shaft 33 and upon the rise of the actuators 31 to nearly the limit of their upward stroke the cam-node 51 then strikes the arm 49 for the purpose of rotating the shaft 46, and thereby causing the bar 52 to swing all of the hammers 36 away from the punches and to thereby draw all-ofthe selectors 37 away from the master-sheet. The relative adjustment of the parts is of course such that the bar His lifted just prior to the time at which the bar 52 engages the lower ends of the hammers 36 to pullthe selectors away'from As soon as the fingers of the selectors are free from the master-sheet the latter is then'given the previously-ex plained intermittent unit of feeding movement, and the selectors are then again released and allowed to swing toward the tracker-board under the tension of the springs 39. Certain of the selectorswill then again engage perforations in the master-sheet, while others will encounter imperforate portions of the mastersheet. The locking-bar 1 1 then immediately engages the selectors to preserve-their relative positions during the operation of the punches. The paper 72 is, as'previously explained, given an intermittent feeding movement in unison with the master-sheet, and the feeding movement of both paper and mastersheet occurs, of course,-during the interval when the actuators 31 are up and the selectors 37 pulled back from the tracker-board.

It will be understood, of course, that the bar 52 constitutes a means for rendering all of the hammers 36 inoperative during the feeding movement of the paper and master-sheet and that the selectors constitute the means for determining which of the hammers shall beoperated during the downward movement of the actuators 31. Said hammers or impact devices 36 may be regarded as power-transmittmg connections between the actuators and the punches which can be rendered inoperative or operative, according to the number of punches to be actuated' These power-transmitting connections between the actuators and the punches can of course be con trolled or reg ulated in various ways. In the present case they are controlled by a master-sheetthrough the medium of the selectors 37 for the purpose of reproducingperforated music. If de-.

sired, however, any other means, either automatic or manual, can be employed for controlling the said hammers.

Inasmuch as the selectors are drawn away from the master sheet during the feeding movement of the latter, it follows that the said master-sheet can be of comparatively thin paper and that an ordinary piece of perforated music, either in its original form or with slight modification and reconstruction, can be employed as the master-sheet. In other words, ihe selectors are so Well controlled that there is no liability of their tearing or injuring the to bear flatwise upon the master-sheet and also to bear against the inner edges 73 of the reinforcing-strips 29, which are secured to the marginal portions of the master-sheet. In

this way these feet or pressing portions act as Spreaders to maintain the master-sheet in a perfectly smooth and flat condition while traveling upward across the tracker-board and over the roll 28.

With the increasing popularity of the pianoplayer it is becoming desirable and, in fact, necessary that the perforated music, which is the most important feature of the player, he sold at as reasonable a figure as possible. A machine of the foregoing character is well calculated to reduce thecost of perforated music without in any way impairing the quality of the latter. In other words, a machine of the character herein described is adapted to produce a high grade of perforated music at a comparatively small cost of manufacture.

With further respect to the unitary and self-contained die-and-punch structure it will be seen that the two guide-bars 6 and 7 can be held together by screws 74: and that ordinary dowel-pins 75 can be employed for pre- @serving the proper relation between these two guide-bars 6 and 7 and the base or body portion 3. In this way the die-and-punch structure as a whole can be easily taken apart and put together.

With further respect to the master-sheet and tracker board it will be seen that the presser-feet can bear upon the main surface of the master-sheet and also upon the surface of the reinforcing-strips applied to the edges or marginal portions of the master-sheet. The toothed formation of the reinforced edges of the master-sheet, together with the toothed idlers, insure a proper and accurate feeding movement of the master-sheet, it being understood that the teeth on the edges of the master-sheet correspond to or bear 'a certain predetermined relation to the units of feed. This is a very advantageous feature of my invention, as it insures a proper feeding movement of the master-sheet, as well as a smooth and perfectly flat condition of the same at all, times during its upward travel upon the tracker-board.

As previously explained, the herein described machine is designed for the purpose of reproducing the perforations of a pattern or master-sheet in strips of paper, and in this connection it will be understood that the term reproducing is intended to embrace or comprehend, broadly, the manufacture of per forated music by the aid of a pattern or master-sheet regardless of whether or not such pattern or master-sheet has openings of the exact size and location desired for the perforations in the perforated music. In fact,

master-sheet during the feeding movement of IIO the expression reproducing as herein used means merely the reproduction, in the form of perforations in a sheet of paper, of the musical composition represented by openings, perforations, or other devices in a pattern or master-sheet. It is obvious, however, that the toothed wheels and the toothed formation of the master-sheet can be used or not, according to the nature of the work and according to the character of the master-sheet to be employed.

By pivotally connecting therodstl at points some distance above the lower ends of the hammers it is evident that very slight movement on the part of the selectors is sufiicient to give the lower ends of the hammers quite an extent of movement. With the arrangement shown it is also obvious that the selecting and punching operations or actions are of a positive and certain character and of such nature as to permit any desired speed. If the hammers are well finished on their sides, they can then work close together and in such near relation to each other as to practically guide each other in their up-and-down and swinging movements. Furthermore, the blow or impact on each hammer is received practically directly by the member upon which the hammer is mounted rather than by the pivot which carries the hammer. Also it will be seen that the spring-actuated selectors cause the rods 41 to positively pull the hammers into position to engage the punches. In addition the selectors are positively retracted through the medium of the said hammers and rods.

Obviously, with the construction shown the unitary punch-and-die structure can be ad justed bodily and horizontally in a direction at right angles to thedirection of feed of the paper and master-sheet. The said unitary structure can be adjusted in this manner in order to accurately position the punches below the hammers and can then be held in its adjusted position by means of the set-screws12 and 13 or by means of any other suitable or desired devices. It will be seen that the punches are organized into a structure which is, by reason of the dowel-pins 75. readily removable as a unit from the structure comprising the die.
